8-Aminoquinoline as a bidentate traceless directing group for Cu-catalyzed selective B(4,5)–H disulfenylation ofo-carboranes

Chemical Communications, Год журнала: 2020, Номер 56(85), С. 12997 - 13000

Опубликована: Янв. 1, 2020

A traceless bidentate directing group guided copper catalyzed direct cage B(4,5)-H disulfenylation of o-carboranes has been achieved, leading to a series B(4,5)-disulfenylated o-carborane derivatives in high yields with excellent regioselectivity. The situ departure the 8-aminoquinoline auxiliary circumvents additional processes for removal, thus enhancing atom-/step-economy.

Directing Group Assisted Transition Metal Catalyzed Selective BH Functionalization of o-Carboranes

Synthesis, Год журнала: 2024, Номер unknown

Опубликована: Июнь 11, 2024

Abstract Carboranes are a type of molecular clusters consisting carbon, hydrogen, and boron atoms. They possess unique characteristics, such as three-dimensional aromaticity, icosahedral geometry, robustness. Functionalized carboranes have been utilized in various fields, including medicine, materials, organometallic/coordination chemistry. In this context, selective functionalization o-carboranes has received tremendous attention, specifically the regio- enantioselective modification ten chemically similar BH vertices within carborane cage. recent years, significant progress made catalytic vertex-specific functionalization, well achieving cage BH. This review provides an overview advancements research field. 1 Introduction 2 Carboxy-Assisted Functionalization 2.1 Formation B–C Bonds 2.2 B–N 2.3 B–O 2.4 B–X 2.5 Consecutive B–Y (Y = N, O) 3 N-Based Directing-Group-Assisted B–H 3.1 Acylamino Directing Group 3.2 Amide 3.3 Pyridyl 3.4 Imine 4 Phosphinyl-Assisted Cage 5 Bidentate-Directing-Group-Assisted 6 Other 7 Conclusions
